What do we hear when we change the direction of a wire?


Douglas Self wrote a devastating article about audio anomalies back in 1988. With all the necessary knowledge and measuring tools, he did not detect any supposedly audible changes in the electrical signal. Self and his colleagues were sure that they had proved the absence of anomalies in audio, but over the past 30 years, audio anomalies have not disappeared anywhere, at the same time the authority of science in the field of audio has increasingly become questioned. It's hard to believe, but science still cannot clearly answer the question of what electricity is and what sound is! (see article by A.J.Essien).

For your information: to make sure that no potentially audible changes in the electrical signal occur when we apply any "audio magic" to our gear, no super equipment is needed. The smallest step-change in amplitude that can be detected by ear is about 0.3dB for a pure tone. In more realistic situations it is 0.5 to 1.0dB'". This is about a 10% change. (Harris J.D.). At medium volume, the voltage amplitude at the output of the amplifier is approximately 10 volts, which means that the smallest audible difference in sound will be noticeable when the output voltage changes to 1 volt. Such an error is impossible not to notice even using a conventional voltmeter, but Self and his colleagues performed much more accurate measurements, including ones made directly on the music signal using Baxandall subtraction technique - they found no error even at this highest level.

As a result, we are faced with an apparently unsolvable problem: those of us who do not hear the sound of wires, relying on the authority of scientists, claim that audio anomalies are BS. However, people who confidently perceive this component of sound are forced to make another, the only possible conclusion in this situation: the electrical and acoustic signals contain some additional signal(s) that are still unknown to science, and which we perceive with a certain sixth sense.

If there are no electrical changes in the signal, then there are no acoustic changes, respectively, hearing does not participate in the perception of anomalies. What other options can there be?

However, this thread from what I can tell is not at all a matter of physics, or electrical transmission, but one of psychology. Convincing yourself you heard a difference without doing the truly hard work of both isolating the changes you made, and removing your knowledge of the change a listening test demonstrates that your perceived sonic differences are no more than feelings, but do not evidence an actual physical change, or an actual change in what you heard (as opposed to what you thought you heard). That is a matter of psychology, not physics.
Yes, bias)) You have copied the meaning of the very first answer on this topic.

It is rather pointless to engage in a discussion such as this without some adequate effort to recreate the experiment and control for manufacturing variance and visual listening.

Then make some adequate effort and check the capabilities of the player, the directivity of a wire or whatever. Some people have already done this and are discussing the topic on the point. You are welcome.

doogiehowser, no one can prove anything to anyone here. Either you hear it yourself, or you don’t. If don’t then this branch is not for you.
